Launch X-431 PRO DYNO – Professional Automotive Diagnostic Scanner

The Launch X-431 PRO DYNO is a professional 8-inch automotive diagnostic scanner designed for workshops, mechanics, and automotive technicians. It combines OE-level full-system diagnostics, bi-directional Active Tests, advanced ECU Coding, 37+ service functions, AutoVIN, live data, and support for modern vehicle communication protocols.

Yes. The PRO DYNO provides OE-level full-system diagnostics on compatible vehicles. It can access systems such as Engine, Transmission, ABS, SRS/Airbag, Body Control Module, headlights, windows, ADAS, and many other available electronic control modules.

The scanner can access supported ECUs to read and clear fault codes, retrieve ECU information, display live data, and perform vehicle-specific diagnostic procedures. This provides much more comprehensive troubleshooting than a basic OBD-II code reader.

Yes. The PRO DYNO features bi-directional control, also known as Active Tests. It can send commands directly to supported vehicle ECUs and actuators, allowing technicians to test components and locate faults more efficiently.

Available Active Tests vary by vehicle but can include lights, door locks, fuel injectors, fuel pumps, coolant pumps, windows, windshield wipers, EVAP components, and many other electronically controlled actuators.

Yes. The PRO DYNO supports advanced ECU Coding on compatible vehicles. Depending on the vehicle, technicians can use coding functions for module matching, relearning, calibration, recoding, personalization, and configuration after component or ECU replacement.

On supported vehicles, yes. After replacing certain ECUs or electronic modules, the PRO DYNO can provide the required matching, learning, coding, or calibration functions so that the replacement component can operate correctly with the rest of the vehicle.

On compatible vehicles, ECU Coding can provide vehicle personalization and configuration functions. Available options depend entirely on the vehicle and may include configuration of convenience, lighting, display, window, and other factory-supported features.

The PRO DYNO provides 37+ maintenance and service functions for supported vehicles. The exact functions available depend on the vehicle manufacturer, model, model year, ECU, and installed diagnostic software.

Available functions can include commonly required workshop procedures such as Oil Reset, EPB Reset, BMS/Battery Reset, Steering Angle Calibration, ABS Bleeding, Injector Coding, DPF Regeneration, Throttle Adaptation, TPMS-related functions, and many other manufacturer-specific reset and relearn procedures.

Yes. The PRO DYNO supports AutoVIN on compatible vehicles. It can automatically identify information such as the vehicle make, model, and manufacturing year, helping technicians enter the correct diagnostic software more quickly.

Yes. The PRO DYNO supports graphical live data and provides a Combine function that can display up to four data streams together on one interface. This makes it easier to compare related sensor values and identify abnormal vehicle behavior.

Yes. The PRO DYNO supports CAN FD, allowing it to communicate with compatible newer vehicles that use this high-speed automotive communication protocol.

Yes. The PRO DYNO supports DoIP (Diagnostics over Internet Protocol) for compatible vehicles. According to the product information, a suitable DoIP adapter/cable is required for DoIP communication.

Yes. The PRO DYNO supports FCA SGW applications. Access to protected functions on compatible FCA vehicles may require the appropriate authorization, account, or subscription depending on the vehicle and service being performed.

The PRO DYNO features an 8-inch 1280 × 800 display, Android 10 operating system, 2.0 GHz quad-core processor, 4 GB RAM + 64 GB storage, and a 6300 mAh battery. It uses the Launch DBScar VII diagnostic connector and supports both wireless and wired VCI connections.

Yes. The PRO DYNO includes 2 years of free software updates. After the free update period expires, the scanner can continue to be used with the software already installed, while access to newer software updates requires renewal.

Yes. The PRO DYNO can be expanded with compatible Launch accessories, including X-PROG3, TSGUN and RF sensors, BST360 Battery Tester, VSP600 Videoscope, O2-2 Scopebox, S2-2 Sensorbox, ADAS equipment, Wi-Fi Printer, and Launch Key Programmer. Optional accessories are sold separately unless specifically included in a bundle.

Yes. The PRO DYNO supports expansion with the compatible Launch SmartLink C HD Lite Heavy Duty Truck Module. This makes it possible to extend the diagnostic platform to supported commercial and heavy-duty vehicle applications when the appropriate hardware and software are used.

The Launch X-431 PRO DYNO combines OE-level full-system diagnostics, bi-directional Active Tests, advanced ECU Coding, 37+ service functions, AutoVIN, graphical live data, CAN FD, DoIP capability, FCA SGW support, and extensive accessory expansion options in a compact 8-inch platform. With 4 GB + 64 GB memory, a 6300 mAh battery, DBScar VII, and two years of free updates, it is a versatile professional solution for everyday workshop diagnostics.
